The U.S. Secret Service has launched an investigation after Republican presidential nominee Donald Trump’s former butler called for the death of President Barack Obama through his Facebook post.

Anthony Senecal wrote in a Facebook post that Mr Obama should have been taken out by U.S military and shot as an enemy agent in his first term.

Anthony Senecal spent 17 years as Donald Trump’s personal butler.

Senecal has not served as a butler to the billionaire candidate since 2009, but he was identified in a March 15 profile in the New York Times as a current employee of Mar-a-Lago, serving as the estate’s historian.

Donald Trump’s campaign denounced Thursday “horrible statements” made by his longtime butler Anthony Senecal calling for President Obama to be killed.

According to a statement released Thursday by a campaign spokesperson says that Tony Senecal has not worked at Mar-a-Lago for years.
